Specification of Letters Patent.

To all whom 'it may concern:

Be it known that I, GEORGE W. DUNHAM, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Venftilators, of which the following is a specitication, reference being had therein to the accompanying drawings.

The Vinvention relates to ventilators for automobile bodies, and consists particularly in the construction of a device for inducing a current of air in the forepart of the automobile body behind the dashboard or hood, as more fully hereinafter described and particularly pointed out in the claims.

In the drawings-Fi ure 1 is a perspective view of a portion OI an automobile body of well-known type, showing my invention applied thereto; Fig. 2 is a perspective view of the deflector; Fig. 8 is a vertical section centrally throughthe deiector and the dashhood; and Fig. 4 is a similar section, on line t1-m of Fig. 1.

At the present time there is a well-known type of automobile body, such as shown in Fig. l, A. being the body proper, B the seat, C the bonnet, D the front doors at the sides, E an inclined hood which extends forwardly from the bonnet C over the dash. In automobile bodies of this kind, having side-doors at the front, the heat radiated from the engine-which is in the bonnet immediately in front of the dash-at times becomes excessive and unpleasant upon the feet of the people occupying the front seat. My device is intended to provide air circu lation beneath the hood and in rear of the dash, to overcome this objectionable overheating.

In order to induce this air current by the forward motion of the car, I attachvto the upper edge of the hood E a curved defie'ctor F-preferably of U-shape in cross-section, as clearly shown in Fig. 3. This deiector is provided, preferably at the ends, with lugs G on opposite sides, embracing the edge of the hood, and which may be secured thereto by suitable bolts II or by other means. The delector thus shaped passes around the edge of the hood E a short distance therefrom,

so as to form a curved passage I-through which the air, in the motion of the car, will enter and be delivered on the underside oi' the hood, in the path shown by the arrows.

It will be observed that whenever the car is in motion the air which will be deiiected up on the upper side of the hood will pass beneath this delector and be carried down the swiftly-moving current across the rear of the dash-board and expel the hot air which naturally would accumulate around the feet of the occupants of the front seat.

Il; is also obvious that this device may be removed by simply taking olf the bolts by which it is attached, and thus when it is not desired for use may be quickly dispensed with.

What I claim as my invention is- 1. In an automobile, the combination with lthe dash-hood, of a curved deflector embracing the upper edge of said hood and spaced therefrom, said delector having portions extending on both sides of said hood for deliecting the air current induced by the motion of the car from the outer side of said hood tothe inner side thereof.

2. 'Ihe combination in an automobile of the front dash and a deecting device applied thereto, said delecting device embracing an edge of said dash and extending onl both sides of said dash for defiecting the air induced'on one side of the dash by the motion of the car to the opposite side of said dash.

3. rI`he combination ir. an automobile of a front dash and a cuT ved deiector applied to the upper edge thereof, said deiiector having a portion extending above the upper edge of the dash opening toward the front of the automobile, and a portion extending below the upper edge of the dash for deiecting theair bythe motion of the car downward adjacent the rear side of the dash.
